  • Capacitor bias recovery methodology
    Patent number: 6452455
    Abstract: The present invention provides an apparatus, system and method of improving the bias response time for pre-amplifier circuits which utilize noise reduction capacitors 275. The system uses a quick recovery circuit 210 electrically connected to the capacitive node 216 of the pre-amplifier circuit. The quick recovery circuit 210 comprises a gain amplifier 218 with a resistive input and a controlled current source 219. The controlled current source corresponds to adjustments in a controlled current source 225 of the pre-amplifier and is electrically connected to the resistive input of the gain amplifier 218. The gain amplifier 218 can be selectively switched 211 to operatively connect an output to the capacitive node 216 of the pre-amplifier circuit.
